HSE3 & E6 Aluminium Housed ARCOL manufactured Aluminium Housed Resistors are now available with threaded terminals and supplied with fixing kit as standard. M3 terminal avaliable on the 25 & 50 Watt resistors & M6 terminal on the 75 to 150 range. High Power to volume Wound to maximise High Pulse Capability Values from R005 to 100K Custom designs welcome RoHS Compliant Characteristics Tolerance (Code): Standard 5% (J) and 10% (K). Also available 1% (F), 2% (G) and 3% (H) Tolerance for low values: Typically R05 5% R047 10% Temperature coefficients: Typical values < 1K 100ppm Std. > 1K 25ppm Std. For lower TCRs please contact Arcol Insulation resistance (Dry): 10,000 M minimum Power dissipation: At high ambient temperature dissipation derates linearly to zero at 200C Ohmic values: From R005 to 100K depending on wattage size Low inductive (NHS): Specify by adding N before HS Series code, e.g. NHS50 NHS ohmic value: Divide standard HS maximum value by 4 NHS working volts: Divide standard HS maximum working voltage by 1.414 Temp. Rise & Power Dissipation Heat Dissipation Surface temperature of resistor related to power dissipation. Heat dissipation: Whilst the use of proprietary heat sinks The resistor is standard heatsink mounted using a proprietary with lower thermal resistances is acceptable, uprating is not heatsink compound. recommended. For maximum heat transfer it is recommended that a heat sink compound be applied between the resistor 200 HS300 base and heat sink chassis mounting surface. It is essential that the maximum hot spot temperature of 200C is not exceeded, HS150 HS250 HS50 HS200 therefore, the resistor must be mounted on a heat sink of HS25 correct thermal resistance for the power being dissipated. 100 HS100 HS75 HS15 HS10 Ordering Procedure 5 Standard Resistor.
