4611H-701-121/560L

Overview

The Bourns 4611H-701-121/560L is a through-hole RC network terminator housed in an 11-pin SIP package. It integrates ten resistor-capacitor elements with a resistance of 120 ohms and capacitance of 56 picofarads per channel. The components utilize C0G dielectric capacitors with a temperature coefficient of 30ppm/Cel and ±20% tolerance. Resistors offer ±5% tolerance within a standard range up to 470K ohms, supporting a maximum operating voltage of 50 volts.

Feature Summary

• Provides low noise termination specifically designed for CMOS applications
• Integrates combined resistors and capacitors into a single SIP package to save space
• Includes insulation resistance testing to ensure component reliability

Applications

• Low noise termination for CMOS circuits
• Electromagnetic interference (EMI) suppression
• First-order low-pass filtering in electronic circuits

Procurement Notes

Verify the specific pin count and element configuration against the datasheet, as the 4611H series includes variants with different pin counts ranging from 4 to 16. Confirm that the 120 ohm resistance and 56 picofarad capacitance values match the circuit requirements exactly. Ensure the through-hole mounting style and SIP package dimensions are compatible with the target PCB layout before finalizing procurement.

Selection Notes

Select this component when a dedicated RC terminator is required for CMOS signal integrity or EMI filtering. The 11-pin SIP format consolidates multiple passive elements, reducing board space compared to discrete components. Verify that the 50-volt maximum operating voltage and ±5% resistor tolerance meet the system's electrical constraints and performance standards.

Part Context

This part belongs to the Bourns 700 Series of RC Terminator Networks. The series offers various pin counts from 4 to 16, allowing designers to choose configurations based on channel density. These networks are engineered to provide consistent impedance matching and noise reduction in high-speed digital interfaces.

Replacement Considerations

Check for other parts within the 4611H series that share the same 120 ohm resistance and 56 picofarad capacitance but differ in pin count. Ensure any substitute maintains the SIP form factor and through-hole mounting characteristics to fit existing footprints without redesign.
