The Perun Micro MOSFET represents a significant leap in gearbox electronics engineering. This ultra-compact mosfet unit channels battery current directly to the motor whilst mechanical contacts handle only signal switching—a design philosophy that fundamentally improves reliability and performance in any AEG build.
Key Features
- Smallest MOSFET device on the market – fits tight gearbox spaces
- Ultra-low resistance transistor – maximises motor efficiency and ROF
- Extended mechanical contact lifespan – reduces arcing and wear
- Direct battery-to-motor power channelling – minimises voltage drop
- Improved replica reliability – fewer electrical failures in the field
- Easy integration – compatible with standard gearbox wiring
Real-World Use Cases
CQB skirmishers benefit from the increased rate of fire without sacrificing trigger responsiveness. Milsim players appreciate the reliability boost during extended gameplay sessions. Upgraders retrofitting older AEGs find the compact footprint allows installation where larger electronics would be impossible. Target shooters value the consistency that reduced electrical resistance provides shot-to-shot.
Technical Specifications
- Device type: Ultra-low resistance MOSFET transistor
- Form factor: Micro (smallest available)
- Power delivery: Direct battery-to-motor channelling
- Contact protection: Signal-only mechanical switching
- Installation: Standard AEG gearbox compatible
Compatibility & Upgrades
The Perun Micro MOSFET integrates into any standard AEG gearbox. It works seamlessly with most battery types and motor configurations. Consider pairing with a quality lipo battery and appropriate charger to maximise the performance gains this MOSFET delivers. For builds running high-torque motors or demanding ROF setups, this unit’s low-resistance design is particularly advantageous.
UK Legal & Site Notes
MOSFETs are internal electronics modifications. Ensure your site operator permits electronic upgrades, and always chrono your replica after installation to verify FPS compliance with your local site limits. Most UK sites accept gearbox electronics without issue when the replica remains within power limits.
