Overview
The VFR3VD31E131T51B is a three-channel low-pass EMI filter from the Murata VFR3 series, designed for electrostatic discharge (ESD) surge protection of integrated circuits. It features a capacitance value of 130 pF and a peak surge current rating of 20 mA. The device operates within a temperature range of -25°C to +85°C and has a DC voltage rating of 25 VDC with a varistor voltage of 50 V. Packaged in bulk, its dimensions are 8.00 mm in length and 2.00 mm in width.
Feature Summary
- Provides efficient absorption of ESD surges entering IC I/O terminals
- Features three independent channels for multi-line signal protection
- Designed specifically for protecting sensitive integrated circuits
Applications
- ESD surge protection for IC input/output terminals
- General purpose EMI/RFI filtering applications
- Protection of electronic components against electrostatic discharge events
Procurement Notes
Verify the part status as obsolete before procurement planning. Confirm that the bulk packaging format meets assembly requirements. Ensure the 20 mA surge current and 130 pF capacitance specifications align with the target circuit design constraints. Check for available substitute components due to end-of-life status.
Selection Notes
Select this component when three-channel ESD protection is required for integrated circuits. The 130 pF capacitance suits high-speed data lines where minimal signal distortion is needed. Verify that the 25 VDC rating and 50 V varistor voltage are sufficient for the operating environment. Consider the -25°C to +85°C operating range for environmental compatibility.
Part Context
This component belongs to the Murata VFR3 series, which is part of the EMIFIL and EMIGUARD product lines. These filters are engineered to protect semiconductor devices from transient voltage spikes. The specific model utilizes a low-pass topology to attenuate high-frequency noise while maintaining signal integrity on protected lines.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Due to the obsolete part status, consult Murata technical support or authorized distributors for current equivalent recommendations.
