Physical Structure and Build of RC0805FR-07110KL

The RC0805FR-07110KL is constructed with a high-quality ceramic substrate that provides thermal and mechanical stability. Internal metal electrodes are integrated on each end of the chip to establish reliable electrical contact with the thick film resistive element. The resistive layer is developed using noble metal-glass composites, ensuring durability and performance stability. It is then covered with a secondary glass layer to shield against environmental effects.

A protective epoxy coat finalizes the process, enhancing mechanical integrity and long-term reliability. External terminations are finished with a matte tin plating over a nickel barrier, providing superior solderability and resistance to oxidation—a critical aspect for surface-mount technology (SMT) assembly lines. Each resistor is laser-trimmed for precision, ensuring the delivered resistance meets the specified 1% tolerance.

Electrical Specifications and Performance Metrics

The RC0805FR-07110KL delivers stable electrical performance in a range of circuit conditions:

Resistance value: 110 kΩ

Tolerance: ±1%

Power rating: 0.125 W (1/8 W) at 70°C

Maximum working voltage is determined by the formula:

V = √(P × R), where P is rated power (W) and R is resistance (Ω), limited by the series’ maximum voltage capability.

This model can operate reliably in ambient temperatures from -55°C to +155°C. The device is ideal for handling continuous DC or AC (rms) loads, with performance derating applied at elevated temperatures. Users can consult YAGEO’s published power derating curves for precise guidelines in thermal management and reliability assurance during design stages.

Labeling and Part Number Identification for RC0805FR-07110KL

Efficient tracking and assembly of the RC0805FR-07110KL is facilitated through clear marking conventions. For 1% tolerance parts in the E24/E96 range, YAGEO uses a four-digit code system: the first three digits denote the significant figures, and the fourth digit indicates the multiplier (number of zeros). For example, a marking of “1103” corresponds to 110 kΩ. This marking is critical for automated assembly and visual inspection in high-mix SMT production environments.

Installation Guidelines and Packaging Varieties

To optimize solder joint reliability and board utilization, the RC0805FR-07110KL is designed for standard 0805 (2012 metric) SMT footprints. For mounting, YAGEO recommends following their “Chip resistors mounting” guidelines, which address soldering profiles and PCB pad dimensions suitable for both reflow and wave soldering.

In terms of packaging, the RC0805FR-07110KL is typically supplied on embossed taping reels, a format that supports high-speed automated pick-and-place machinery. The resistor can be sourced in standard packaging quantities, supporting prototyping and volume manufacturing requirements alike.

Environmental Standards and Product Reliability

The RC0805FR-07110KL is engineered for compliance with international environmental regulations:

Full RoHS and halogen-free compliance, with lead-free manufacturing processes

Eliminates hazardous materials, contributing to safer end products and eco-friendly supply chains

Tested in accordance with industry standards for temperature cycling, humidity, moisture resistance, and mechanical endurance

With a moisture sensitivity level (MSL) of 1, the resistor is tolerant to typical moisture exposure environments, minimizing storage and handling constraints for procurement and assembly teams.

Alternative or Substitute Models for RC0805FR-07110KL

When selecting alternatives or replacements for the YAGEO RC0805FR-07110KL, engineers can consider resistors from the broader YAGEO RC_L series offered in similar sizes (0805), resistance values, and power ratings. Other mainstream manufacturers also offer compatible thick film chip resistors with 110 kΩ value, 1% tolerance, and 0805 packaging. Key considerations when cross-referencing replacements are:

Resistance value and tolerance match

Power rating and voltage capability

Footprint compatibility

Environmental and quality certifications

Marking and packaging options

Verifying datasheets for electrical, mechanical, and environmental equivalence is essential for ensuring drop-in replacement without compromising product performance or qualification status.
