ACTBPDR4V
Panasonic ACTBPDR4V automotive relay, 1 Form A at 12 V DC coil, switching 30 A at 14 V DC with sealed pin-in-paste mounting.
The ACTBPDR4V is a Panasonic ACT series automotive relay with a 12 V DC coil and a 1 Form A (SPST-NO) contact arrangement, built for the 12 V vehicle electrical system. It is a compact, sealed relay that switches up to 30 A at 14 V DC, and its silver-alloy contacts with a copper clad layer can handle the inrush of a capacitive load, which is common in a vehicle where a relay switches a lamp, a motor or an electronic module. The sealed body survives the vibration and the wide temperature range of an automotive environment, and the relay is pin-in-paste compatible so it can be reflow soldered with the rest of the board. The compact footprint suits a body-control module where space is tight, and the 1 Form A contact is the standard arrangement for a high-side or low-side load switch. A designer chooses an automotive relay by the coil voltage, the switching capacity, the inrush rating and the sealing, and by the terminal arrangement that fits the harness or the board. The ACT series is used in body electronics, lighting, HVAC and other 12 V loads, and it is a direct alternative to a micro-ISO relay where a board-mount part is preferred. Every relay BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file, and mainstream ratings are held in stock.
FAE Professional Review
The ACTBPDR4V is a sealed automotive relay for a 12 V board, and its value is the pin-in-paste mounting and the capacitive-inrush capability, which let it switch a lamp or a module directly. Confirm the inrush rating for your load and the coil drive, and remember that the sealed body is what survives the vehicle environment.

Frequently Asked Questions
What is the ACTBPDR4V rated for?
It is a 1 Form A (SPST-NO) automotive relay with a 12 V DC coil, switching up to 30 A at 14 V DC, in a sealed pin-in-paste compatible case for the 12 V vehicle system.
Confirm the inrush rating for your load.
Can it handle a capacitive inrush?
Yes. The silver-alloy contacts with a copper clad layer are sized to handle the inrush of a capacitive load, which is common when a relay switches a lamp or an electronic module in a vehicle. Check the inrush figure against your load before you commit.
Read the relay selection guide.
Is the relay genuine and in stock?
BeiLuo supplies factory-traceable relays through Panasonic authorized channels, with import declaration, certificate of origin and RoHS files on every order. Mainstream ratings are normally in stock.
