High-Efficiency 12-Cavity Magnetron

The 2M219J magnetron is a direct replacement component for select Midea and compatible microwave ovens. Dimensions: 125 mm × 85 mm × 60 mm (L×W×H); weight: approx. 420 g; operating voltage: 4 kV (typical anode supply); filament voltage: 3.3 V AC; output power: 850–900 W at 2450 MHz. Constructed with high-purity copper anode block, ceramic insulators, and nickel-plated external casing for thermal stability and corrosion resistance. This magnetron features a proven 12-cavity resonant design that delivers consistent microwave energy output and improved heating efficiency compared to older 8- or 10-cavity units. Its variable-frequency-compatible operation supports intelligent power modulation in compatible ovens—enabling automatic adjustment of output level based on load and food type. Installation uses standard mounting holes and common electrical interfaces (including filament leads and anode cap), requiring no modification to the oven chassis or control board. Ideal for restoring full heating performance in domestic microwaves showing weak or uneven heating, and suitable for sustained use in light commercial environments such as cafés, staff kitchens, and catering facilities where reliability and minimal downtime are essential.
