Overview
The KNH21C105DA3TS is a three-terminal feed-through capacitor from the KYOCERA AVX KNH21 series, designed for EMI filtering in compact surface-mount applications. It features a 1 µF capacitance with a tolerance of -20% to +50%, rated for 10 VDC. The component utilizes an 0805 (2.0 x 1.25 mm) package with a maximum height of 0.85 mm. It supports a rated current of 4.0 A and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Three-terminal feed-through architecture provides effective electromagnetic interference suppression.
Applications
- High-speed data line noise filtering
- Power supply input filtering
- Compact electronic device EMI mitigation
Procurement Notes
This component is officially discontinued and no longer manufactured by KYOCERA AVX. Verification of availability should focus on surplus or secondary market sources rather than direct factory orders. Designers must confirm end-of-life status and plan for immediate part substitution due to unavailability in standard distribution channels.
Selection Notes
Selection requires evaluating alternative components that match the 0805 footprint and three-terminal configuration. Key parameters to verify include equivalent capacitance, voltage rating, and current handling capabilities. Engineers should prioritize parts with similar thermal characteristics and low impedance profiles to maintain circuit performance without redesigning the PCB layout.
Part Context
The KNH21 series represents KYOCERA AVX's ultraminiature feed-through capacitors engineered for high-frequency noise suppression. These components integrate a ground terminal between signal terminals to minimize parasitic inductance. The series is specifically optimized for space-constrained environments requiring robust EMI/RFI protection in digital and analog circuits.
Replacement Considerations
Official substitutes are not confirmed in public documentation. Verify cross-references with other 0805 three-terminal filter capacitors ensuring identical pinout and electrical ratings to prevent compatibility issues.
