SBSPP1000221MCT

Overview

The Knowles Syfer SBSPP1000221MCT is an EMI filter circuit designed for surface mount applications. It features a Pi-filter topology with C0G dielectric capacitors rated at 220 pF and ±20% tolerance. The component supports a maximum DC voltage of 100 V and handles up to 1 A of current. Housed in a compact 1206 (3216 metric) package, it operates within a temperature range of -55°C to +125°C. The unit provides 14 dB of attenuation and measures 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height.

Feature Summary

• Integrates a Pi-filter network structure for effective electromagnetic interference suppression
• Utilizes stable C0G (NP0) ceramic dielectric material for consistent performance
• Supports high current handling capability suitable for power line filtering

Applications

• Electromagnetic interference filtering in electronic circuits
• Signal integrity protection in high-frequency applications
• Power supply noise reduction in compact devices

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with surface mount assembly processes. Check for RoHS compliance status through authorized channels. Confirm packaging options such as cut tape or reel availability directly with suppliers. Validate operating temperature ranges against application requirements before procurement.

Selection Notes

Select this component when a compact EMI solution is required for low-voltage, high-current lines. The 1206 footprint offers space efficiency compared to larger packages. Consider the 14 dB attenuation level for moderate noise suppression needs. The C0G dielectric ensures minimal capacitance variation over temperature and voltage. Evaluate the 1 A current rating against peak load conditions in the target circuit design.
