1806J1000273MJTE07

Overview

The Knowles Syfer 1806J1000273MJTE07 is a multilayer ceramic feed-through capacitor designed for surface-mount applications. It features a capacitance of 0.027 µF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in the 1806 (4516 metric) package, it measures 4.5 mm in length, 1.6 mm in width, and 1.1 mm in height. This device is rated for 2 A current handling and serves as a three-terminal EMI filter.

Feature Summary

• Integrates three-terminal architecture for effective electromagnetic interference suppression
• Utilizes C0G (NP0) dielectric for high stability and low loss characteristics
• Supports continuous current loads up to 2 Amperes
• Designed for surface-mount technology integration

Procurement Notes

Verify the complete part number including the suffix to confirm specific packaging and termination specifications. Ensure compatibility with automated placement equipment regarding the 1806 footprint dimensions. Confirm that the 100V DC rating and 2A current capacity meet the target circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when high-current filtering capability is required alongside standard MLCC form factors. The C0G dielectric ensures minimal capacitance drift under varying thermal conditions. Consider the 1806 package size constraints relative to available PCB real estate and ensure the 100V rating exceeds the maximum expected circuit voltage.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which combines the benefits of traditional capacitors with integrated inductive properties for superior high-frequency attenuation. These devices are engineered for robust performance in demanding environments, offering reliable shielding against conducted emissions while maintaining compact physical profiles suitable for modern electronics.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 100V rating, 0.027µF value, and 2A current handling. Verify equivalent three-terminal construction and C0G dielectric type to maintain identical filtering performance and thermal stability characteristics.
