Circuit Coditions Spec: 2.1 Drive Level (DL) 500μW max. (If Drive Level is too high,that may cause crystal resonator abnormal oscillation or damagaed the main body of quartz.) 2.2 Loading capacitance (CL) : 20PF (The total circuit load capacitance should be equal to the crystal (CL) values, too large or too small will result in frequency drift.) 2.3 Negative Resistance (-R) ≥ 125Ω (If –R more than ESR spec of 5 times will be better. If Negative Resistance is too low, that may cause resonator stop oscillation or not easy to oscillate) SHENZHEN SCTF ELECTRONICS CO.，LTD DATE 2021-9-30 Specification of quartz crystal 石英晶体谐振器规格书 P/N: SXMH25.000F2020F30 Spec.NO.: SCTF2021T617 Page: 3 ■ DIMENSIONS 4.1MAX Units (单位)：mm(毫米) SHENZHEN SCTF ELECTRONICS CO.，LTD DATE 2021-9-30 Specification of quartz crystal 石英晶体谐振器规格书 P/N: SXMH25.000F2020F30 Spec.NO.: SCTF2021T617 Page: 4 ■ PRODUCT STRUCTURE & MARKING ◆ Product Structure产品规格 ◆ Marking印字 Logo SCTF 25.000 Nominal Frequency (MHz) SHENZHEN SCTF ELECTRONICS CO.，LTD DATE 2021-9-30 Specification of quartz crystal 石英晶体谐振器规格书 P/N: SXMH25.000F2020F30 Spec.NO.: SCTF2021T617 Page: 5 ■ REFLOW PROFILES Profile Feature Preheat/Soak ●Temperature Min(Ts min) ●Temperature Max (Ts max) ●Time (Ts min to Ts max) Ramp-up rate (TL to Tp) Time maintained above ●Liquidous temperature (TL) ●Time (tL) maintained above TL Peak package body temperature (Tp) Time within 5 °C of the specified classification temperature (Tp) Ramp-down rate (Tp to TL) Time 25 °C to peak temperature Suggust reflow times Sn-Pb Eutectic Assembly Pb-Free Assembly 100 °C 150 °C 60-120 seconds 150 °C 200 °C 60-120 seconds 3 °C/second max. 3 °C/second max. 183 °C 60-150 seconds 235℃ 217 °C 60-150 seconds 20 seconds 30 seconds 6 °C/second max. 6 minutes max. 6 °C/second max. 8 minutes max. 260℃ 2 Times max.
