Works great. Hope this helps you our. **Q: Does it have mounting bolt slots?** A: Hello Sarah, it does have 2 mounting holes, they are at the top and bottom of the bridge rectifier. The mounting holes are inside the heat sink fins, so they cannot be seen from the picture. The holes are 13/64'' in diameter (according to calipers), so #10 (3/16) bolt would fit. There is very little room for a washer, although you may be able to fit a small one. **Q: can i use this in 12v automotive applications?** A: I used it to convert a wire welder to DC. But I would think you could. Have no idea where you would want to use it... **Q: does this rectifier turn ac to dc voltage** A: Yes ## Frequently Bought Together - Baomain 100A Amp 1200V Volt Diode Bridge Rectifier Metal QL100A - Yeeco AC 110V 10000W SCR Electronic Voltage Regulator Motor Speed Control Thermostat Governing Governor dimmer - smseace 20Amp Electric Button Breaker 125/250VAC,Thermal Overload Protector L1 Series with Manual Reset, Waterproof Button Cap L1-20A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/6360781-baomain-100a-amp-1200v-volt-diode-bridge-rectifier-metal-ql100a](https://www.desertcart.kg/products/6360781-baomain-100a-amp-1200v-volt-diode-bridge-rectifier-metal-ql100a) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-07-06*
