1806Y1000123MJTE07

Overview

The Knowles Syfer 1806Y1000123MJTE07 is a multilayer ceramic capacitor (MLCC) from the Y5V series. It features a 12 pF nominal capacitance with a ±20% tolerance (M code). The rated voltage is 50 V DC. The component utilizes a nickel barrier termination system and is housed in a standard 1806 (4516 Metric) surface-mount package. It employs a Y5V dielectric material, characterized by high volumetric efficiency but significant capacitance variation over temperature and voltage ranges.

Feature Summary

• High volumetric efficiency for compact circuit designs
• Nickel barrier termination for reliable solderability
• Y5V dielectric offering high capacitance density

Applications

• General purpose decoupling applications
• Bypass circuits in consumer electronics
• Coupling applications where precise capacitance stability is not critical

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to ensure compatibility with RoHS directives and halogen-free requirements. Confirm that the Y5V dielectric characteristics align with the thermal and voltage derating requirements of the target application, as this material exhibits substantial non-linearity.

Selection Notes

Select this component when space constraints necessitate high capacitance in an 1806 footprint and cost-effectiveness is prioritized over precision. Ensure the operating environment accounts for the Y5V dielectric's sensitivity to temperature fluctuations and applied DC bias, which can significantly reduce effective capacitance.

Part Context

This part belongs to the Knowles Syfer Y5V series, designed for general-purpose applications requiring high capacitance values in small packages. The 1806 case size provides a balance between board space savings and handling robustness compared to smaller footprints, while the 50V rating suits low-voltage digital logic supplies.

Replacement Considerations

Direct replacements must match the 1806 footprint, 12 pF value, 50V rating, and Y5V dielectric type. Verify termination metallurgy compatibility. Cross-referencing with other manufacturers' Y5V 1806 capacitors requires validation of dimensional tolerances and capacitance tolerance bands.
