8-channel 1x10^2Ω to 1x10^15Ω Digital Super Megohmmeter for Testing MLCC Leakage Current
The Hioki SM7810 is an 8-channel 1x10^2Ω to 1x10^15Ω insulation resistance tester for testing leak current on multi-layer ceramic capacitors (MLCC).
The Super MΩ HiTester SM7810 is produced to order. An input/output terminal connection cable*1 is required separately. Please contact your local HIOKI distributor.
*1 Input/output terminal connector/plug and connection cable
• Current input terminal connector and voltage output terminal plug are not included. Voltage input terminal connector is included.
• Input/output terminal connection cables are available in various lengths to suit HIOKI measurement systems. Please consult with your HIOKI distributor.
Test the leakage current of MLCCs at the fastest speed of 6.8ms simultaneously over 8 channels
• Conduct high-speed leakage current testing of large-capacity MLCCs in the high current range (1 mA)
• Improve testing reliability using the contact check function
• Build a flexible system by making best use of the individual settings of each channel
