| 熱敏傳感器 | | | | | |  |  NTC Sensor Thermistor - MLHT Type | | | | | | | FEATURES: | | | | | | | | Low cost, high stability. | | | | | The UHT series thermistors is a high-performance thermal sensing device. | | | Excellent thermal cycle endurance and they small B-value tolerance and resistance. | | | | | They insure temperature precision of ±0.3℃ and can be employed for very accurate temperature control or compensation. | | No adjust between the control circuit and the sensor. | | | | | They are also useful for insert to PCB in the constant length. | | | | | | | SPECIFICATIONS | | | | | | | | | Temperature rating | -40℃ to 250℃ | B value :3250K~4750K | | | | Determined by rated zero-power | | | | Resistance at 25℃ and 85℃ | | | | R25 | B25/85 (Ω) | Tolerance ±1% ±2.5% ±5 % | | | |
| 2K | 50K | Dissipation constant Min. 0.7mW/℃ Still air | | | | Rated zero-power, | 5K | 100K | Thermal time constant 5 seconds in still air. | | | | Resistance value at 25'C | 10K |
| Maximum power Rating 10~15mw at 25℃ | | | |
| 15K | | | | | | | 20K | | | | | | | Order Map | | | | | | | Series | MLHAT | 202 | F | -□□□□ | | Res Value (4). | | | | (1) | (2) | (4) | (5) | (6) | | 102 = | 1K ohm | | | | Series Code | TS Type | Res .value | Tolerance | B value | | 103 = | 10K ohm | | | | SINLOON | Diode | at 25℃ | F : 1% | 25℃/85℃ | | 104 = | 100K ohm | | | | Sensor | Thermistor | 10 x 1000 Ω | H : 3% | | | 105 = | 1M ohm | | | | | | | J : 5% | | | | | | | | | | | | | | | | | | | | | 電阻-溫度特性：NTC的電阻值可以隨溫度的上升而下降，由於其溫度係數非常大，所以可以檢知微小的溫度變化，因此被廣泛應用在溫度的量測、控制與補償。 | | | | | | | |
