PBV1632S-3DBN8

Overview

The PBV1632S-3DBN8 is a surface-mount attenuator manufactured by Susumu, designed for RF and microwave applications. It provides a nominal attenuation of 3dB with a tolerance of +/-0.5dB at a characteristic impedance of 50 ohms. The component operates within a frequency range from DC to 3 GHz and has a maximum power handling capability of 100mW. Constructed using silicon technology, it is housed in a 1206 (3216 metric) SMD package. The device supports operation temperatures ranging from -55°C to +125°C and features a maximum VSWR of 1.3.

Feature Summary

• Provides precise 3dB signal attenuation for RF circuit matching
• Operates reliably across a wide temperature range up to 125°C
• Maintains low voltage standing wave ratio for signal integrity

Applications

• RF signal level control in wireless communication systems
• Impedance matching networks in microwave circuits
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific suffix variant against the required datasheet specifications. Confirm that the 1206 package dimensions align with the PCB footprint design. Ensure the 100mW power rating meets the thermal requirements of the target application environment. Check RoHS compliance status if restricted substances are a concern for the assembly process.

Selection Notes

Select this component when a fixed 3dB attenuation is required in a 50-ohm system operating up to 3 GHz. Consider the 1206 package size for space-constrained layouts. Evaluate the 100mW power limit against peak signal levels. Compare performance metrics such as VSWR and temperature stability against alternative attenuators in the same series for optimal circuit performance.

Part Context

This part belongs to Susumu's PBV series of thin-film chip attenuators. These components are engineered for high reliability in demanding electronic environments. The series offers various attenuation values and package sizes to suit different RF design needs. Susumu utilizes advanced thin-film technology to ensure consistent performance and precision across the product line.

Replacement Considerations

Compatible substitutes include other 3dB, 50-ohm, 1206 package attenuators from Susumu or other manufacturers. Verify electrical parameters such as attenuation value, power rating, and frequency response before substitution. Ensure mechanical compatibility with the existing PCB layout.
