1812J2000472MJTE03

Overview

The Knowles Syfer 1812J2000472MJTE03 is a feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 4700 pF and a voltage rating of 200 VDC, with a tolerance of ±20%. The component operates within a temperature range of -55°C to +125°C and utilizes a C0G (NP0) dielectric material. Housed in an SMD/SMT package with dimensions of 4.5 mm x 3.2 mm x 2.5 mm, it supports a maximum current of 50 mA. This Class 1 multilayer ceramic device is engineered for reliable performance in demanding electronic environments.

Feature Summary

• Provides effective high-frequency noise attenuation through integrated feed-through architecture
• Maintains stable electrical characteristics across wide operating temperatures using C0G dielectric
• Supports continuous current loads up to 50 mA for robust circuit integration

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering in compact surface-mount designs
• Signal integrity protection in communication equipment

Procurement Notes

Verify the complete part number including the suffix MJTE03 to ensure correct specification matching. Confirm that the 50 mA current rating aligns with your circuit requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 1812 footprint matches your PCB layout constraints before procurement.

Selection Notes

Select this component when high-frequency noise reduction is critical in space-constrained applications. The 4700 pF value offers significant filtering capability while maintaining low impedance at target frequencies. Consider the 200 VDC rating for appropriate voltage headroom. The C0G dielectric ensures minimal capacitance variation over temperature and voltage changes.

Part Context

This component belongs to the Knowles Syfer 1812J series of feed-through capacitors. These devices integrate capacitor functionality directly into the mounting structure, eliminating the need for separate ground connections. The series is designed for applications requiring superior high-frequency performance compared to traditional MLCCs.
