This product has been DISCONTINUED TK/TN Series Discontinued May 2013 Product will be available till existing stock is depleted. 20 and 15 Watt TO-220 Package Thick and Thin Film 0.394" (10mm) 0.177" (4.5mm) Specifications 0.004" (0.1mm) 0.591" (15mm) 0.701" (17.8mm) 0.031" (0.8mm) 0.039" (1.0mm) 0.201" (5.1mm) Ohmite is proud to introduce the newest addition to our family of Heat Sinkable Power Resistors. The TK/TN Series offers 3 major advances over existing TO-220 products: • Low Resistance Values down to 0.03 ohms for current sense applications • Low Cost • Thin Film Construction is the first Thin Film power resistor in heatsinkable packaging on the market. W H Y T H IN F I L M ? Thin film technology offers the following performance advantages: • Extremely stable (low TCR) • Low Noise (parasitic capacitance and resistance) • Excellent High Frequency Performance • High Accuracy (tight tolerances) 0.287" (7.3mm) Patent pending Bracket 6200E: recommended mounting bracket kit (optional) 0.180" (4.57mm) Material Resistive element: Thick or thin film chip resistor Terminals: Tin plated copper (100Sn) Case: Ryton Heatsink plate: Black anodized aluminum Electrical Thick film TK20 Thin film TN15 Power rating: 20W 15W (Heat-sink dependent; must be attached to a proper heat sink for full power rating.
