RCN02M1PPEA3

Attenuators Overview

The RCN02M1PPEA3 is a fixed chip-type attenuator manufactured by ROHM Semiconductor, designed for radio frequency and microwave applications. It features a π-type construction with three integrated chip resistors to provide a nominal attenuation of 16 dB at a characteristic impedance of 50 Ω. The device supports a maximum continuous wave input power of 16.02 dBm and maintains a maximum voltage standing wave ratio of 1.3. It operates within a temperature range of -55 °C to 125 °C and is compliant with RoHS standards.

Attenuators Feature Summary

• Utilizes a π-type architecture integrating three chip resistors for signal attenuation
• Provides guaranteed attenuation accuracy with tolerance options of ±0.3 dB or ±0.5 dB
• Reduces mounting area by 50% compared to single discrete resistor types
• Ensures high reliability in sulfur environments through specialized internal structure

Attenuators Applications

• RF signal path attenuation in wireless communication systems
• Microwave circuit impedance matching and signal level control
• High-reliability electronic equipment requiring sulfur tolerance
• Automotive radar and sensor signal conditioning

Attenuators Procurement Notes

Verify the specific suffix code against the manufacturer's latest datasheet to confirm exact attenuation tolerance and package variant. Ensure the ordering part number matches the required 16 dB specification and 50 Ω impedance. Confirm compliance with project-specific environmental standards such as AEC-Q200 if used in automotive contexts. Check for any design changes or obsolescence notices prior to final procurement.

Attenuators Selection Notes

Select this component when space constraints require a compact solution for fixed RF attenuation. The π-type design offers superior performance compared to single-resistor alternatives by reducing mounting area significantly. Consider the ±0.3 dB or ±0.5 dB tolerance options based on system precision requirements. Ensure the operating temperature range aligns with the application environment, particularly for high-temperature scenarios up to 125 °C.

Attenuators Part Context

This component belongs to the RCN02 series of chip-type attenuators from ROHM Semiconductor. The series is engineered to replace multiple discrete resistors with a single surface-mount device, simplifying assembly and improving consistency. It is categorized under passive components for radio frequency and microwave circuits, offering a reliable alternative to traditional lumped-element designs.

Attenuators Replacement Considerations

Direct substitutes include other ROHM RCN02 series variants with different attenuation values or tolerances. Cross-brand replacements must match the 50 Ω impedance, 16 dB attenuation, and 0404 package dimensions. Verify that alternative components meet the same thermal and electrical specifications, including the 16.02 dBm power handling limit and 1.3 VSWR requirement.
