Littelfuse 2029L100
The 2029L/3425L Series Resettable devices utilize a unique polymer-based, Positive Temperature Coefficient (PTC) material to protect electrical circuits against overcurrent conditions. This dramatically reduces the conductive paths resulting in an immediate rise in resistance.| Part No. | 2029L100 |

RESETTABLE PTCs SURFACE MOUNT PTC 2029L/3425L Series ® ® TUV PRODUCT SERVICE
●
● In normal operation, the 2029L/3425L Series PTC has many conductive paths and a very low resistance. In an overcurrent condition, the temperature of the polymer material rises. In this condition, the device provides circuit protection by significantly limiting the flow of current. However, once the cause of the initial overcurrent condition is eliminated, the 2029L/3425L Series PTC cools down and resets to a low resistance value permitting the normal current flow to resume.
● The 2029L/3425L Series are surface mountable. AGENCY APPROVALS: Recognized under the Components Program of Underwriters Laboratory and the Component Acceptance Program of CSA. TUV approved. AGENCY FILE NUMBERS: UL E183209, CSA LR 108832 PHYSICAL SPECIFICATIONS: Materials: Terminal Material: Tin Plated Brass to MIL-T-10727B Lead Solderability: Meets EIA specification RS186-9E Device Labeling: Device is marked with the letter ‘L’, amperage rating and date code.
