4609H-701-101/101L

Overview

The Bourns 4609H-701-101/101L is an RC network terminator designed for low noise termination in CMOS applications. It features a single-termination circuit configuration housed in a 9-pin Single Inline Package (SIP) for through-hole mounting. The component integrates resistors and capacitors to provide efficient electromagnetic interference filtering while saving board space. Key electrical parameters include a resistance of 100 ohms with ±5% tolerance, a capacitance of 0.0001 µF (100 pF), and a maximum operating voltage of 50 volts. The capacitor utilizes C0G temperature characteristics with a coefficient of 30ppm/°C.

Feature Summary

• Provides low noise termination specifically optimized for CMOS circuits
• Integrates combined resistors and capacitors within a compact SIP package to save space
• Reduces insertion time during assembly processes
• Undergoes insulation resistance testing to ensure reliability

Applications

• Low noise termination for CMOS logic circuits
• EMI filter networks requiring first-order low-pass characteristics
• High-density PCB designs utilizing Single Inline Packages

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as /470L exist with different capacitance values. Confirm current availability status as this series may be subject to restricted supply or obsolescence. Ensure the selected pin count matches the target circuit requirements, as the 700 series offers configurations from 4 to 16 pins. Cross-reference datasheets for exact mechanical dimensions and thermal ratings before finalizing procurement.

Selection Notes

Select this component when designing CMOS interfaces that require effective signal termination and noise reduction. The 100-ohm resistance value aligns with standard transmission line impedance requirements. Consider the 9-pin SIP form factor for applications needing multiple terminated channels in a single footprint. Verify that the 50-volt maximum operating voltage meets the system's electrical stress conditions.

Part Context

This part belongs to the Bourns 700 Series of RC Terminator Networks. The series is characterized by its ability to combine passive components into unified SIP structures. Other models in this family vary by pin count, resistance values ranging from 0.22 ohms to 470K ohms, and capacitance options. The series is designed to replace discrete resistor-capacitor arrangements in high-reliability electronic assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Variants within the same series, such as the 4609H-701-101/470L, share similar physical footprints but differ in capacitance specifications. Engineers must verify electrical compatibility before substituting any component from the broader 700 Series.
