4612H-701-101/101L

Overview

The Bourns 4612H-701-101/101L is a through-hole RC terminator network housed in a 12-pin Single Inline Package (SIP). It integrates 11 resistor-capacitor channels, each configured with a resistance of 100 ohms and a capacitance of 100 picofarads. The component supports a maximum operating voltage of 50 volts and utilizes C0G dielectric capacitors with a tolerance of ±20%. Designed for low noise termination in CMOS applications, it offers a compact solution that reduces insertion time while maintaining high insulation resistance reliability.

Feature Summary

• Integrates combined resistors and capacitors within a single SIP package to save space
• Provides low noise termination specifically designed for CMOS circuits
• Reduces assembly insertion time compared to discrete component implementation

Applications

• Low noise termination for CMOS logic circuits
• EMI/RFI filtering in digital signal lines
• First-order low-pass filter networks

Procurement Notes

Verify the specific suffix designation to confirm pin count and electrical values, as variations exist within the 4612H series. Ensure the ordering code matches the required 100 ohm resistance and 100 pF capacitance specifications. Confirm RoHS compliance status if restricted substance management is required for the target assembly process.

Selection Notes

Select this component when a compact, multi-channel RC termination solution is needed for CMOS interfaces. The 12-pin SIP format suits board layouts requiring through-hole mounting. Consider the 100 ohm/100 pF combination for standard impedance matching and noise suppression requirements in digital systems.

Part Context

This part belongs to the Bourns 700 Series of RC Terminator Networks. The series offers various pin counts ranging from 4 to 16, allowing designers to scale channel density according to circuit complexity. These networks are engineered to replace multiple discrete components, simplifying PCB routing and improving signal integrity in high-speed digital environments.

Replacement Considerations

Cross-reference with other 4612H variants such as 4612H-701-101/121L or 4614H-701-101/101L if different pin counts or capacitance values are acceptable. Verify that substitute parts maintain the same SIP footprint and through-hole mounting characteristics to ensure mechanical compatibility.
