Non-combustible ultra-small metal film resistor "RNS"
Non-flammable ultra-small metal film resistor
[Ultra-Compact, High Power, UL94V-0 Compliant] RNS Series Flame-Retardant Ultra-Compact Metal Film Resistors | Achieving Downsizing of Circuit Boards and High Voltage Resistance
The "RNS series" is an ultra-compact, high-power metal film resistor that achieves an even smaller body size compared to conventional small-sized products. This directly contributes to significant compactness (space-saving) of the mounting board and demonstrates excellent performance in downsizing replacements from traditional metal oxide film resistors. 【Features of RNS】 【Ultra-compact, high-power design】 Contributes to ultra-high density and downsizing of board mounting with an ultra-compact body that is one rank smaller than standard small-sized resistors. 【Excellent high voltage characteristics】 Despite its ultra-compact size, it supports a maximum operating voltage of 400V to 600V (maximum overload voltage of 800V). 【Replaceable with metal oxide film resistors】 Promotes miniaturization and high performance of circuits through replacement of traditional metal oxide film resistors. 【Flame retardant UL94V-0 compliant】 Uses flame-retardant and non-flammable paint (UL94V-0) for the exterior, ensuring safety against ignition and overheating. 【Precision grade tolerance of ±0.5%】 Flexibly accommodates precision specifications with a tolerance of ±0.5% (D rank) and TCR of ±100ppm/℃. *Requests for catalogs and specifications can be accessed via the URL below.
