Product details
The strategically optimized Round - 55.12mm OD x 26.92mm ID dimensions meet strict military packaging requirements while maximizing active cooling area for defense electronics.
With 12.9W @ 25°C of reliable heat transfer capacity, the module maintains critical systems within operational limits even in desert or arctic deployments.
The 67°C @ 25°C maximum temperature difference capability ensures electronics survival during rapid ambient temperature swings encountered in aerospace applications.
At just 3.81mm tall, the low-profile design fits within armored enclosure constraints while withstanding 50G shock impacts.
The 1-stage military-spec configuration provides redundant thermal paths for fault-tolerant operation in critical defense systems.
Designed for harsh environments, the module maintains specified performance at 6 A maximum current during voltage spikes common in military power systems.
The 3.7 V maximum voltage rating accommodates both 28VDC aircraft and 48VDC ground vehicle electrical systems.
Battlefield-proven 570 mOhms stability ensures consistent performance despite vibration-induced micro-fretting in mobile deployments.
Qualified for 80°C operation, the module exceeds typical military temperature range requirements for global deployment.
Military-spec Lead Wires, Non-Sealed provide hermetic sealing and EMI shielding for operation in nuclear, biological, and chemical (NBC) environments.
