2012 sizes,0.6mm in
3216 size) than the multilayer type. z Excellent mountability due to its higher mechanical strength. z Excellent mountability due to its solder plating at the terminal section. z Suitable for both flow and reflow solderings. z Products with lead free termination meet EU-RoHS requirements. EU-RoHS regulation is not intended for Pb- glass contained in electrode, resistor element and glass. 参考标准 Reference Standards IEC 60115-8 JIS C 5201-8 IEC 60539-1 JIS C 2570-1 结构图 Construction ① 保护膜 Protective coating ② 热敏电阻膜 Thermistor ?lm ③ 内部电极 Inner electrode ④ 镀镍 Ni plating ⑤ 焊接电镀 Solder plating ⑥ 陶瓷基板 Ceramic substrate ③ ② ① ④ ⑤ ⑥ L c c W t d 外形尺寸 Dimensions 型号 Type (Inch Size Code) 尺寸 Dimensions (mm) Weight (g) (1000pcs) L W c d t 1J (0603) 1.6±0.2 0.8±0.1 0.3±0.1 0.3±0.1 0.5±0.1 2.54 2A (0805) 2.0±0.2 1.25±0.1 0.4±0.2 0.3 +0.2 C0.1 0.5 +0.2 C0.1 4.87 2B (1206) 3.2±0.2 1.6±0.2 0.5±0.3 0.4 +0.2 C0.1 0.6±0.1 10.12 品名构成 Type Designation 实例 Example NT73 2A T TD
