EZA-ST13AAAJ

Overview

The Panasonic EZA-ST13AAAJ is a surface-mount RC network designed for noise reduction in electronic circuits. It integrates four resistors and four capacitors within a single compact package, functioning as an isolated low-pass filter. The component features a resistance of 22 Ohms per channel and a capacitance of 100 pF per channel, with a rated voltage of 25 V DC. It operates within a temperature range of -25°C to +85°C and utilizes a 1608 (4021 metric) footprint with concave terminals.

Feature Summary

• Integrates multiple passive components into a single surface-mount device to reduce circuit board area
• Provides isolated filtering channels for effective noise suppression on data lines
• Utilizes a compact footprint significantly smaller than discrete chip resistor and capacitor placements

Applications

• Noise reduction on mobile device data lines
• EMI/RFI filtering in portable electronics
• Signal integrity protection in compact consumer devices

Procurement Notes

Verify the specific electrical parameters against the official datasheet before integration, as values such as resistance and capacitance are critical for filter performance. Confirm that the 25V rating and operating temperature range meet the system requirements. Check current availability status as this series may have discontinuation notices or limited stock from distributors.

Selection Notes

Select this component when space constraints prevent the use of discrete resistors and capacitors for low-pass filtering. Ensure the required resistance and capacitance values match the 22 Ohm and 100 pF specifications. Consider the 1608 package size and terminal type for PCB layout compatibility. Verify that the 25V DC rating is sufficient for the signal line voltage.

Part Context

This part belongs to the Panasonic EZA series of chip RC networks, which includes variants like EZACT, EZADT, and EZAST. These networks are engineered to replace multiple discrete components, offering a solution for noise reduction in applications requiring small form factors. The EZA-ST variant specifically features concave terminals for reliable surface mounting.

Replacement Considerations

Check for direct substitutes within the EZA-ST series with different R/C values if impedance matching differs. Verify if newer revisions of the EZA-ST family offer equivalent electrical characteristics and packaging dimensions.
