BPF1005LRQYR3750A

Overview

The BPF1005LRQYR3750A is a passive bandpass filter manufactured by Pulse Electronics. It operates within a frequency range of 3.3 GHz to 4.2 GHz, with a center frequency of 3750 MHz and a bandwidth of 900 MHz. The component features a 50 Ohm impedance and utilizes SMD/SMT termination. It is housed in a 0402 (1005 metric) package with six pins. The device supports board mounting and functions reliably between -40°C and +85°C. Insertion loss is specified at 2 dB.

Feature Summary

• Passive bandpass filtering capability for RF signal conditioning
• Compact 0402 surface-mount footprint for space-constrained designs
• Wide operational temperature range suitable for industrial environments

Applications

• RF front-end modules requiring specific bandpass characteristics
• Wireless communication systems operating in the 3.3-4.2 GHz range
• Signal conditioning circuits in compact electronic devices

Procurement Notes

Verify the exact suffix against official Pulse Electronics documentation to ensure correct pin configuration and passband specifications. Confirm RoHS compliance status through current manufacturer declarations. Check for alternative suffixes such as PK or PP if different electrical parameters are required. Ensure compatibility with automated pick-and-place equipment due to the small 0402 package size.

Selection Notes

Select this component when a narrow bandpass response centered at 3.75 GHz is needed in a minimal footprint. Compare insertion loss and stopband rejection requirements against other BP series variants. Consider the six-pin layout for potential grounding or shielding integration. Evaluate thermal stability needs against the -40°C to +85°C rating.

Part Context

This part belongs to Pulse Electronics' BP Series of bandpass filters. These components are designed for high-frequency applications where size and performance are critical. The series offers various configurations to meet diverse RF filtering requirements across consumer and industrial electronics markets.

Replacement Considerations

BPF1005LRPPR3750L and BPF1005LRPKR3750A are related parts in the same series. Verify electrical parameter differences before substitution.
