0805J0500330MCTE01

Overview

The Knowles Syfer 0805J0500330MCTE01 is a three-terminal feedthrough capacitor designed for surface mount applications. It features a capacitance of 33 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 0805 (2012 metric) package, it incorporates nickel barrier terminations with 100% tin plating. This design provides high-frequency EMI filtering capabilities while maintaining low parasitic inductance.

Feature Summary

• Three-terminal feedthrough architecture for superior high-frequency noise suppression
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage
• Low parasitic inductance structure optimizes RF interference filtering performance

Applications

• High-frequency electromagnetic interference (EMI) filtering in sensitive circuits
• Power supply input/output decoupling for noise reduction
• Signal line protection in communication equipment

Procurement Notes

Verify the specific termination configuration and lead length requirements against the mechanical drawing before integration. Confirm that the selected distributor is an authorized supplier to ensure component authenticity. Check current RoHS compliance status as regulatory updates may occur. Validate thermal management strategies during soldering to prevent damage to the ceramic body.

Selection Notes

Select this component when high-frequency noise attenuation is critical in space-constrained designs. The three-terminal structure offers better performance than standard two-terminal MLCCs at higher frequencies. Ensure the circuit operates within the specified 50V DC limit and temperature range. Consider the physical footprint compatibility with existing PCB layouts during the design phase.

Part Context

This part belongs to the Knowles Syfer feedthrough capacitor series, specialized for EMI suppression. Unlike standard multilayer ceramic capacitors, these components utilize a coaxial internal structure to minimize inductance. They are commonly used in aerospace, medical, and industrial electronics where signal integrity and noise immunity are paramount.

Replacement Considerations

Direct substitutes include other 0805 package feedthrough capacitors from manufacturers like Johanson Technology or Murata. Verify that replacement parts match the 33 pF capacitance, 50V rating, and terminal spacing. Ensure the alternative component meets the same AEC-Q200 or equivalent reliability standards if required by the application.
