SBSPP1000221MCB

Overview

The Knowles Syfer SBSPP1000221MCB is a surface-mount EMI filter circuit designed for high-frequency noise suppression. It features a Pi-filter topology utilizing C0G dielectric capacitors rated at 220 pF with a 20% tolerance. The component operates within a 100 V DC voltage range and supports a continuous current of 1 A. Housed in a compact 1206 (3216 metric) package, it functions reliably across an extended temperature range from -55°C to +125°C. This SMD device provides effective attenuation characteristics suitable for dense PCB layouts requiring robust electromagnetic interference mitigation.

Feature Summary

• Integrates a Pi-filter network structure for enhanced signal integrity
• Utilizes stable C0G dielectric material for consistent performance
• Supports high-current operation up to 1 A in a compact form factor

Applications

• High-speed digital circuit noise suppression
• Power line filtering in sensitive electronic systems
• Signal conditioning in RF communication modules

Procurement Notes

Verify the specific suffix 'MCB' against the official datasheet to confirm packaging and terminal specifications. Ensure compatibility with standard reflow soldering profiles for 1206 packages. Cross-reference the manufacturer's latest documentation for any updates on RoHS compliance status or recommended landing pad dimensions prior to final design approval.

Selection Notes

Select this component when a pre-configured Pi-filter solution is required to save board space and simplify layout. The 1206 footprint offers a balance between thermal dissipation and size constraints. Consider the 1 A current rating and 100 V breakdown voltage to ensure adequate margin for the target application's electrical stress conditions.

Part Context
