Characteristics
describe values that are relevant to the use of the model under stated operating
conditions but are not covered by the model warranty.
•
Typical
specifications describe the performance met by a majority of models.
•
Nominal
specifications describe an attribute that is based on design, conformance testing,
or supplemental testing.

Voltage, Current, and Resistance
Notice
Refer to the specifications of the module with which you are using the
TB-414X to note the maximum voltage and current ratings. The specifications listed
below are the maximum for the TB-414X only.
Channel operating voltage
1
60 V DC
HI/LO pin current
2
3 A
Note
It is critical to ensure that the LO terminal for each channel in use is
connected when the total current from all channels exceeds 3 A. The TB-414X is
rated for the force pins carrying a maximum of 3 A average current, however,
individual pin currents above 4 A may damage or degrade the lifespan of the pins.
Systems that have a common path between the LO of each channel at the DUT end
of the cable must ensure that LO path wiring resistances are matched within ±20% to
prevent the LO terminal of one channel from carrying a significant portion of
another channel’s LO current and exceeding the 4 A individual pin limit.
Force path resistance
3
30 mΩ, typical
Leakage resistance
4
23 °C
>100 TΩ, typical
1
Maximum voltage measured between the HI, HI Sense, LO, LO Sense, or Guard terminals. SMU
specifications take precedence if the SMU model is rated for lower voltage.
2
SMU specifications take precedence if the SMU model is rated for lower current.
3
Combined resistance in the HI and LO force traces and connectors for a channel of the TB-414X.
Does not include any output resistance contributions of the SMU module or user wiring. Refer to
SMU module specifications to determine if this resistance is included in the voltage load regulation
specification or if it should be accounted for separately.
4
Applies between HI and LO terminals. Leakage performance may be degraded for operation above
70% relative humidity. When transitioning a device from a storage or operation environment with
operating humidity above 70%, allow the device to stabilize in the lower humidity environment for
several hours before use.
