我想知道Joel是否知道在8753中使用了什么样的超级电容器（超级电容器）。我没有配备超级电容器的早期8753中的一个，但我刚买了HP 4291B 1.8GHz阻抗/材料分析仪虽然4291B是在日本开发的，但外观和感觉非常像8753。 4291B手册称“电池”充电需要10分钟，持续3天。这听起来类似于早期的8753，它使用了超级杯。我担心安装的电容可能是错误的类型。电容标记为：* Tokin * FS * * 5.5 V * 1 F * L6（L6是日期代码，但我不知道L6是什么日期）查看Tokin / NEC超级电容的数据表，其中我附上，* FS系列*超级电容器设计用于低阻抗负载，+“备用1小时或更短时间”+ - 几乎不是4291B手册所说+电池+设计的3天。我很想用FYH0H105ZF替换这个几乎肯定是FS0H105ZF的电容，这是一个相同的电容（1 F），电压（5.5 V），引脚间距（10.16 mm），但来自* FY系列*，专为更高阻抗负载而设计，具有长期备份。在足够低的电流下，FY系列可以具有大约3 x 10 ^ 8 ^秒的备用时间，这是10年！相比之下，FS系列的备用时间比其短几个数量级。我想知道*过去是否有人替换了电容器并且安装了错误的类型。 * HP有充分的理由使用FS系列电容 - 也许FY系列不存在。 *我忽略了Dave编辑：drkirkby于2016年1月2日12:04 PM编辑：drkirkby于2016年1月2日下午12:17 以上来自于谷歌翻译 以下为原文I wonder if Joel knows what sort of super capacitor (supercap) was used in the 8753. I don't have one of the early 8753's which is fitted with a super capacitor,but I just got an HP 4291B 1.8GHz Impedance/Material Analyser, which looks and feels remarkably like an 8753, despite the 4291B was developed in Japan. The 4291B manual says the "battery" takes 10 minutes to charge and lasts 3 days. That sounds similar to the early 8753's, which used supercaps. I'm concerned that the capacitor fitted may be of the wrong type. The capacitor is marked: * Tokin *FS* * 5.5 V * 1 F * L6 (L6 is the date code, but I don't know what date L6 is) Looking at the data sheet for the Tokin/NEC super capacitors, which I attached, the *FS series* of supercaps is designed for low impedance loads, +"Back-up for 1 hour or less"+ - hardly the 3 days that the 4291B manual says the +battery+ is designed to have. I'm tempted to replace this capacitor, which is almost certainly an FS0H105ZF, with an FYH0H105ZF, which is the same capacitance (1 F),voltage (5.5 V), lead spacing (10.16 mm), but is from the *FY series*, which are designed for higher impedance loads, with longer term backup.At a sufficiently low current, the FY series can have a backup time of about 3 x 10 ^8^ seconds, which is 10 years! In contrast, the FS series is designed for backup times several orders of magnitude shorter than that. I'm wondering if * Someone has replaced the capacitor in the past and fitted the wrong type.* HP had good reason for using an FS series capacitor - perhaps the FY series did not exist.* I'm overlooking something Dave Edited by: drkirkby on Jan 2, 2016 12:04 PMEdited by: drkirkby on Jan 2, 2016 12:17 PM附件NEC-Tokin-supercap-data-sheet.pdf913.7 KB
