＜Features＞
・Resistance remain nearly unaffected by increase of frequency with HFT series.(In case of regular thermistor, reduction
of resistance is observed with increase of frequency) Usable in high-frequency band(～１０GHz）.
・Wrap-around terminals (tinned surface) same as regular chip components offer easy mounting and high reliability.
・Highly reliable package sustaining thermistor with firm ceramic has been adopted, so that firm structure has been
realized against environmental influence and phisical impact.
・RoHS compliance. Perfect lead-free has been fulfilled although it is difficult with a thermistor.
