Coating color : Green (1H, 1E)
Black (1F, 1J, 2A, 2B, 2E, W2H, W3A)
•Small and light weight.
•Excellent heat resistance and weather resistance, because of the use of glaze thick film as resistive film.
•High stability and high reliability because of the triple-layer structure of electrode.
•Applicable to various kinds of automatic mounters for taping, etc.
•Suitable for both flow and reflow solderings.
•Products with lead free termination meet EU-RoHS requirements.
EU-RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass.
• AEC-Q200 Qualified(Except 1F).

For resistors operated at an ambient temperature of 70°C or above, a current
rating shall be derated in accordance with derating curve on the left.
For resistors operated at an terminal part temperature of described for each size or above, a current rating shall be derated in accordance with derating curve.
※ Please refer to “Introduction of the derating curves based on the terminal part temperature” before use.
