Robust Kovar Alloy Construction: Engineered from a premium iron-nickel-cobalt alloy for exceptional durability and thermal stability.
Hermetic Glass-to-Metal Seal: Provides an impermeable barrier against moisture, gases, and contaminants, ensuring long-term reliability.
Specialized Non-Spherical Cap: Designed for precise optical applications, allowing for tailored light paths and superior focus compared to standard spherical caps.
Standard TO-46 Footprint: Guarantees seamless compatibility with existing manufacturing processes and automated assembly equipment.
Gold-Plated Leads: Ensures superior electrical conductivity and outstanding resistance to oxidation and corrosion.
Versatile Application Base: Ideal for protecting sensitive components like photodiodes, phototransistors, and integrated circuits in demanding environments.
In the world of high-precision electronics, the integrity of your final product hinges on the protection of its most sensitive components. Imagine the core of your device—a delicate photodiode or a specialized sensor—exposed to the harsh realities of its operating environment. Fluctuations in temperature, microscopic moisture particles, and corrosive elements can silently degrade performance, leading to failure and costly recalls. This is where our TO-46 Non-Spherical Cap Shell becomes not just a component, but a guardian of your innovation.
Crafted from the formidable Kovar alloy, this housing feels solid and dependable in your hand. Its unique composition is no accident; it’s meticulously chosen for its thermal expansion properties, which perfectly match those of the glass seal. This synergy creates a hermetic seal that is virtually unbreakable, a fortress that locks performance in and keeps the world out. You can feel the confidence that comes from knowing your sensitive electronics are encased in a shield designed to withstand thermal cycling and mechanical stress.
What truly sets this shell apart is its non-spherical cap. While a standard dome diffuses light, our specialized cap is a canvas for optical precision. It is the solution for engineers who need to control, direct, and focus light with absolute accuracy. Whether you are designing a medical sensor that requires a direct line of sight or an industrial device that needs to minimize light scatter, this cap provides the foundation for unparalleled optical performance. It’s the difference between a device that simply works and a device that excels, offering clarity and precision where it matters most. This is more than a metal case; it’s a commitment to excellence, reliability, and the pursuit of perfect performance.
Uncompromising Seal Integrity
The heart of this housing is its hermetic glass-to-metal seal. By utilizing Kovar alloy, whose thermal expansion coefficient is precisely matched to the sealing glass, we eliminate the risk of seal failure caused by temperature variations. This creates an airtight and vacuum-tight enclosure, safeguarding your components from humidity, oxygen, and other airborne contaminants that are the primary causes of long-term degradation in sensitive electronics.
Engineered for Optical Precision
The non-spherical cap is a deliberate design choice for advanced optoelectronic applications. It allows for the integration of flat windows, custom-shaped lenses, or specific optical filters directly into the cap’s geometry. This enables engineers to design systems with minimal light distortion, enhanced signal-to-noise ratios, and highly focused light paths, which is critical for applications like medical diagnostics, high-speed data communication, and scientific instrumentation.
Built for Longevity and Reliability
Durability is built into every aspect. The robust Kovar body provides excellent mechanical strength, resisting shock and vibration. Furthermore, the three leads are meticulously plated with a layer of high-purity gold. This not only ensures a low-resistance, stable electrical connection but also provides exceptional resistance to tarnishing and corrosion, guaranteeing reliable performance over the product’s entire lifespan, even in challenging conditions.
Seamless Manufacturing Integration
Designed to the exacting standards of the industry-standard TO-46 package, this shell integrates effortlessly into your existing production lines. There is no need for retooling or process adjustments. Its standard dimensions ensure compatibility with all standard die-attach equipment, sealing ovens, and testing handlers, allowing you to enhance your product’s performance without disrupting your manufacturing efficiency.
This versatile component is the go-to solution for a wide range of industries requiring robust and precise packaging. Its unique design makes it particularly suitable for:
High-Sensitivity Photodiodes: The non-spherical cap allows for a flat or custom window, maximizing light collection efficiency and reducing optical aberrations for accurate light measurement.
Precision Phototransistors: Ideal for optical switches and isolators where a controlled and focused light path is essential for fast switching speeds and high gain.
Infrared (IR) Sensors and Emitters: The hermetic seal protects sensitive IR components from environmental interference, while the cap shape can be optimized for specific beam angles.
Temperature and Pressure Sensors: Provides a stable, sealed environment necessary for the accurate and repeatable operation of MEMS and other solid-state sensors.
Custom Integrated Circuits (ICs): Offers a protective, high-reliability package for specialized ASICs or mixed-signal ICs operating in harsh industrial, automotive, or aerospace environments.
