What are the key features of MOV-07D470K?
- 93 V clamping voltage MOV provides fast transient overvoltage protection for 30 V RMS rated circuits
- 2.5 J energy absorbing capacity handles repetitive surge and ESD transient events on power and signal lines
- 7 mm disc through-hole package with 9 mm x 11 mm dimensions for easy PCB integration in protection circuits
- REACH compliant metal oxide varistor suitable for global distribution in consumer and industrial electronics
What is MOV-07D470K used for?
The Bourns MOV-07D470K is used as a transient voltage suppressor in 24 V DC power supplies, industrial sensor interfaces, and consumer electronics AC/DC adapters to clamp voltage spikes from ESD events, inductive load switching, and conducted lightning transients. Its 7 mm disc form factor and 93 V clamping voltage make it a standard protection component across signal and power entry points in HVAC controllers, LED drivers, and motor control modules rated for 30 V RMS operation. The 2.5 J energy capacity allows it to absorb repetitive transients without degradation in typical industrial and home appliance protection circuits.

Frequently Asked Questions
What clamping voltage and energy rating does the Bourns MOV-07D470K provide for surge protection?
The Bourns MOV-07D470K has a 93 V clamping voltage and a maximum energy absorbing capacity of 2.5 J. The 93 V clamp engages during transient overvoltage events to protect downstream components in circuits rated for up to 30 V RMS, while the 2.5 J energy rating allows it to absorb the transient energy from ESD events and conducted lightning surges without failure in typical low-voltage power protection applications.
For which circuit protection scenarios on 24 V DC industrial systems is the MOV-07D470K most effective?
The MOV-07D470K is effective for protecting 24 V DC industrial control circuits, PLC I/O modules, and 24 V sensor power rails against inductive switching transients from solenoids and relays, which can produce voltage spikes of 100 V to 300 V lasting microseconds. Placed across the power supply terminals or signal input pins of a 24 V industrial module, the 93 V clamping threshold activates in nanoseconds to divert transient energy away from sensitive semiconductor components, meeting the requirements of IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity standards.
How does the 7 mm disc size of the MOV-07D470K compare to larger disc MOVs in terms of energy handling trade-offs?
The 7 mm disc size of the MOV-07D470K offers a compact through-hole footprint suitable for PCB-mounted protection circuits where board space is limited, but its 2.5 J energy rating is lower than larger 10 mm or 14 mm disc MOVs that can absorb 4 J to 20 J per event. For circuits subject to frequent high-energy transients exceeding 2.5 J, such as those on AC mains lines or outdoor industrial equipment exposed to direct lightning coupling, a larger disc MOV would be required to avoid gradual MOV degradation and premature failure over the product service life.
