vishay 自己产的成品标准电阻





FEATURES
• Temperature coefficient of resistance (TCR):
To ±0.3 ppm/°C (+15°C to +45°C) (see Table 1)
• Max TCR: 10 to 30 ppm window (see Figure 3)
• Resistance range: 1Ω to 150 kΩ (for higher and lower
values, please contact Applications Engineering)
• Available up to six significant digits (e.g., 9K99962)
• Resistance tolerance available for ordering: to
±0.005% (50 ppm)
• High accuracy: to 10 ppm (see Table 1)
• Stability: ±0.0005% (5 ppm) at 25°C, 12 months
• No humidity effect: resistive element hermetically
sealed against moisture
• Small size and robust construction
• Direct plug-in device for most DMM’s available in the
market
• Each unit is supplied with certificate of accuracy(1)
• RF shielded case
• Four terminal constructions with an additional
ground socket
• Vishay Foil resistors are not restricted to standard
values; specific “as required” values can be
supplied at no additional cost or delivery time
(e.g., 1K23456 vs. 1K)
• Thermal stabilization time <1 s (nominal value achieved
within 10 ppm of steady state value)
• Electrostatic discharge (ESD) at least to 25 kV
• Rise time: 1 ns effectively no ringing
• Current noise: 0.010 μVRMS/V of applied voltage
(<-40 dB)
• Voltage coefficient: 0.1 ppm/V
• Non inductive: 0.08 μH
• Non hot spot design

一盒5个不知道要多少刀拉？

wangruiguang 发表于 2014-10-10 21:40:19

这个好 估计不便宜吧

simon51 发表于 2014-10-10 21:40:32

山寨这个如何，盒子容易，就是香蕉插头不好搞，里面放金封，应该不必他差吧{:142_381:}

接屏蔽地(GUARD)用的

marshallemon 发表于 2014-10-11 11:57:42

价格肯定不菲吧

mingyu40 发表于 2014-12-15 22:56:29

多少$?n
