Additional Information
Datasheet Resources Samples
The miniASMDC is small-sized 1812 PPTC series, helping
to reduce weight of wire harnesses. PPTC devices
distributed in a circuit can allow the use of smaller wire
sizes with the resulting harnesses. Forego looping back
and forth around a fuse box and place your protection
wherever you see fit. The solid state composition of
PPTC devices helps provide reliability.

Solder Reflow Recommendations
Solder Reflow
Recommended reflow method: IR, hot air, nitrogen.
Recommended maximum paste thickness: 0.25mm (0.010in)
Devices can be cleaned using standard methods and aqueous solvents.
Experience has shown the optimum conditions for forming acceptable solder fillets occur when a reasonable amount of solder paste is placed underneath
each devices termination. As such, we request that customers comply with our recommended solder pad layouts.
Customer should validate that the solder paste amount and reflow recommendations meet its application.
We request that customer board layouts refrain from placing raised features (e.g. vias, nomenclature, traces, etc.) underneath PolySwitch devices. It is
possible that raised features could negatively impact solderability performance of our devices.
Rework
Standard industry practices. (Please also avoid direct contact to the device.)

Disclaimer Notice - Information furnished is believed to be accurate and reliable. However, users should independently evaluate the suitability of and test each product selected for their own applications. Littelfuse products are
not designed for, and may not be used in, all applications. Read complete Disclaimer Notice at www.littelfuse.com/disclaimer-electronics.
WARNING
Users should independently evaluate the suitability of and test each product selected for their own application.
Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
These devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions
or prolonged trip events are anticipated.
Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices.
Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic
components.
PPTC devices are not recommended for installation in applications where the device is constrained such that its PTC properties are inhibited, for example in rigid potting materials or in
rigid housings, which lack adequate clearance to accommodate device expansion.
Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of the device.
